Definitions
- the invention relates generally to devices such as an electric motor, which by through a transmission, acts on the piston of a hydraulic cylinder forming an element of output for the assembly, elastic assistance means, which, in parallel vis-à-vis the electric motor, act on one of the organs constituting the transmission, and the mechanical means of compensation, which ensure a controlled modulation of the action elastic assistance means on the organ in question the transmission.
- control devices find in particular their application for controlling the clutch of a vehicle automobile, as described for example in the documents FR-A-2,523,743, 2,564,920 and 2,541,793 (US-A-4,878,396, US-A-4,671,400).
- the electric motor When controlling the release of such a clutch, the electric motor ensures, through the transmission and output element, positioning suitable for the release bearing, the output element acting for example accordingly on the range of declutching usually associated therewith, however, under control of mechanical compensation means, means assist elastics develop the necessary axial force to balance the opposing force due to the diaphragm of the clutch.
- the mechanical means of compensation advantageously allow these elastic means to be adapted assistance with the specific characteristics of the diaphragm.
- the invention relates more particularly to the case where the element outlet is a hydraulic cylinder, which advantageously allows to more easily catch up with effects due to wear inevitable friction linings of the friction disc of the clutch, and on the piston of which the electric motor acts through transmission. This is the case, by example, in documents FR-A-2 611 615 and 2 614 661.
- the transmission has two organs, namely a worm, which is locked in rotation on the output shaft of the electric motor, and a toothed wheel, against which the worm intervenes tangentially, and to which is articulated, in the manner a connecting rod, a pusher acting on the piston of the jack hydraulic, however that together the means compensation mechanics result from the fact that the means assist elastics act at a point on this wheel angularly spaced apart from the point at which it is articulated push button in question.
- the subject of the invention is a control device of the kind concerned advantageously likely to be reduced in size and also having other advantages.
- This control device is characterized in that mechanical means of compensation comprise at least one train of rollers, which, rotatably mounted around a fixed axis orthogonal to the axis of the hydraulic cylinder, comprises, away from this fixed axis, at least two rollers, namely, a first roller established in contact with a first tray which, linked in movement to the organ concerned with the transmission, is axially movable between two positions, one at a distance, the other projection, and a second roller established in contact with a second plate, on which the elastic means bear assistance, and which, while being stalled in rotation on the first plate, is mounted axially movable relative to this one.
- mechanical means of compensation comprise at least one train of rollers, which, rotatably mounted around a fixed axis orthogonal to the axis of the hydraulic cylinder, comprises, away from this fixed axis, at least two rollers, namely, a first roller established in contact with a first tray which, linked in movement to the organ concerned with the transmission, is axial
- the control device thus formed can advantageously have a relatively compact size reduced, both axially and transversely. It is all the more so as its main constituents, namely the electric motor, the spring constituting in practice the elastic assistance means, and the hydraulic cylinder, can advantageously extend along the same axis.
- the transmission occurring between the electric motor and the hydraulic cylinder piston has two bodies in relation to screw-nut one with respect to the other, which is also favorable to a reduction of overall dimensions, both axially and transversely.
- control device is preferably formed, separately, on the one hand, a mechanical sub-assembly, which includes the motor electric, transmission, elastic assistance means and the mechanical means of compensation, and, on the other hand, a hydraulic sub-assembly, which is attached to the sub-assembly mechanical, and which comprises the hydraulic cylinder.
- the cylinder body hydraulic is engaged axially in the sub-assembly mechanical, and, in addition to further reducing the axial size of the assembly, the body of this jack hydraulic can then advantageously form, if desired, a cylindrical guide bearing for the first plate of mechanical means of compensation, for the benefit of the conditions of these.

- the fixed axis A2 is materialized by a shaft 49 mounted rotating in the body 21 of the housing 20.
- the two plates 39A, 39B extend transversely by relative to the axis A1 of the hydraulic cylinder 14, coaxially with this one.
- the first plate 39A extends on the side of the bottom 26 of the body 21 of the housing 20, and the second plate 39B on the side of the cover 22 of this housing 20.
- the first plate 39A forms a flange at the end of a bowl 40, and the threaded sleeve forming the member 16 of the transmission 12 is backed by a flange 41 at the bottom 42 of this bowl 40, being fixed to this bottom 42 by screws 43.
- the first plate 39A is thus integral, both in translation in rotation, of the member 16 of the transmission 12.
- the bowl 40 has a slightly diameter greater than the outside diameter of the cylinder body 27 hydraulic 14, and, by its outlet, it is engaged on this one.
- the body 27 of the hydraulic cylinder 14 can form a cylindrical guide bearing surface 45 for the first tray 39A.
- this upright 46 has an internal bore axially 47 blind, to receive the threaded rod 34, for the benefit of axial compactness of the assembly.
- the surfaces through which the upright 46 and the piston 13 of the hydraulic cylinder 14 axially bear one on the other are spherical, to compensate for a possible obliquity between the axis A3 of the electric motor 11 and that Al of the hydraulic cylinder 14.
- the elastic assistance means 15 comprise a spring 48, of the coil spring type, coaxial with the jack hydraulic 14. This spring 48 extends around the sleeve threaded forming the member 16 of the transmission 12.
- the mechanical compensation means 17 comprise two roller trains 37, which are arranged in positions diametrically opposed to each other on the one hand and on the other side of the axis A1 of the hydraulic cylinder 14, being symmetrical to each other with respect to this axis A1, and which both intervene between the two plates 39A, 39B.
- the two rollers 38A, 38B of each of these trains of rollers 37 are rotatably mounted between two cheeks 50, around axes parallel to the corresponding fixed axis A2, and they intervene in the same diametral plane relative to the jack hydraulic 14.
- the two rollers 38A, 38B are established in a triangle with the fixed axis A2.
- each of the roller trains 37 comprises, obliquely, at away from its fixed axis A2, a ramp 51, which is interposed on the path of the first plate 39A between its positions moved back and advanced.
- the first plate 39A bears on this ramp 51 by means of a spring 52, here a leaf spring, which is then under stress.
- the spring 52 is attached by rivets 53 on the first plate 39A, on the side thereof opposite the second tray 39B.
- the ramp 51 of each of the roller trains 37 is formed by the edge of the cheeks 50 thereof, and it belongs to a spout 56 formed by these cheeks 50 on the side of the fixed axis A2.
- the bottom 26 of the body 21 of the housing 20 carries, annularly, on its internal surface, around the body 27 of the hydraulic cylinder 14, a ring 57, of elastic material, for form a limit stop for the first plate 39A when the latter is in the advanced position, Figure 6.
- the piston 13 of the hydraulic cylinder 14 is subjected to a return spring 58 which, resting on the blind bottom of the body 27 of this hydraulic cylinder 14, constantly urges it towards the upright 46 of the mechanical sub-assembly 10A.
- the body 27 of the hydraulic cylinder 14 is in connection with a pipe 61 capable of connecting it to the clutch to be controlled.
- the hydraulic cylinder 14, and, more precisely, the body 27 thereof, is otherwise under the control of a solenoid valve 63, which, when energized, i.e. when electrically powered, is closed.

- R B be the radius of the assembly on which this roller 38B is then located with respect to the axis A1 of the hydraulic cylinder 14.
- the roller 38A of the roller trains 37 is located jointly on a radius R A less than the preceding radius R B.
- the spring 48 constituting the elastic assistance means 15 is buttressed by the threaded sleeve constituting the member 16 of the transmission 12, this threaded sleeve being duly positioned by the threaded rod 34, and held in position axial by it, under the control of the electric motor 11.
- the spring 48 is therefore in practice ineffective.
- the spring 48 elastic assistance means 15 accompanies the member 16 of the transmission 12 in its axial displacement, by jointly subjecting it to an axial force assistance F 'which, in parallel with the axial force that jointly develops the electric motor 11 by via the transmission 12, allows movement concomitant axial of the piston 13 of the hydraulic cylinder 14, and, therefore, an increase in the pressure in the body 27 of this jack hydraulic 14.
- this axial assistance force F ′ is in the following relation with respect to the axial force F actually developed by the spring 48, taking into account the multiplying coefficient due to the offset radial between the rollers 38B, 38A of the roller trains 37 of these mechanical compensation means 17:
- F ' F x R AT R B
- the radius R B decreases, while the radius R A remains substantially constant.
- This representative curve thus looks like the curve characteristic of the diaphragm of the clutches, which allows the pressure in the body 27 of the hydraulic cylinder 14 to be at any time best suited to such a diaphragm.
- This solenoid valve 63 also allows a catch-up wear, by a corresponding supply to the cylinder hydraulic 14.
- the guidance of the first plate 39A is provided by balusters 65 duly provided for this purpose parallel to the axis A1 of the jack hydraulic 14 and integral with the body 21 of the housing 20.
